hi all... i'm getting this issue when trying to jboss 4.2.3.ga (jdk1.6). it works fine in tomcat, so i'm thinking there's a clash in the hibernate jars (or something else). if someone has an idea, would be helpful: | pleApplicationEventMulticaster@1e48d65] | 20:32:05,157 INFO [STDOUT] ERROR: org.springframework.web.context.ContextLoader - Context initialization failed | org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookingService': Injection of persistence methods failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating be | an with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/data-source-config.xml]: Invocation of init method failed; nested exception is java.lang.IncompatibleClassChangeError: Class org.hibernate.ejb.Hibernate | Persistence does not implement the requested interface javax.persistence.spi.PersistenceProvider | at org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor.postProcessPropertyValues(Persiste | nceAnnotationBeanPostProcessor.java:324) | at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCap | ableBeanFactory.java:998) | at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCap | ableBeanFactory.java:472) | thx in adv...
